Application filed in, 1a, 191a. Serial No. 297,558.

Elastic Fabrics, of which the following is a full, clear, and exactdescription. V This invention relates to elasticctextile' 10, fabrics,the object being to produce a fabric adapted to he made up into garmentsto be worn next to the body or over the" under' wear of the body, suchfor instance, as

girdles, brassieres, bandages and so forth. or such purposes it isdesirable that the fabric shall not only be elastic, but that it shallbe more or less open in structure, or porous to afford ventilation,while at the same time having sutlicient strength and body to resist-thestrained condition under which such garments are used. Open work orporous fabrics are seldom, if ever. made with elastic cords incorporatedtherein because the cords will not be held from slipping by the textureof such fabrics, and while it is possible to insert rubber cords by handor otherwise into the meshes or loops of certain loosely knit. or lacyfabrics, such fabrics have no practical use for purposes such as abovementioned.

The present invention )rovides a. Way of associating rubber "strandswith threads in such a manner that the rubber will be firmly gripped bythe threads to prevent it from becoming displaced in the fabric and thethreads may be disposed in certain ways to produce the desired open workor porous pattern.

The fabric and the manner of making it will now be explained withreference to the accompanying drawing. in which- Figure 1 is a face viewof a piece of the finished fabric;

Fig. 2 is a similar view of the same piece of fabric as it appears incourse of fabrication in the machine, and Fig. 3 is an enlarged view ofone of the rubber cords covered by a chain stitch as it, appears in thefabric. The fabric comprises rubber cords or strands arranged inparallel relation and spaced apart, the individual cords beingoovere'dfl'or inclosed in individual textlle coverings and the adjacentcords being bfi l'connecfled together by independent cross threads whichinterlock with the threads covering the cbrds and which are arranged ingroupswith intervening spaces. The indivldual covering on the cords canbe put on with sufficient tension to prevent the mbber from slippingwith respect to the covering threads while the lateral or cross threadsbetween the cords can be grouped or spaced as desired to afford thenecessary.

porosity without afl'ccting' the grilp between the rubber and itscovering. n the process of making the fabric, which may be done one warpknitting machine, the rubber strands are held in a considerably extendedcondition so that when finished the natural contraction of the rubberwill draw the threads together and give body to the fabric.

In Fig. 3 a short length of one of the rubber cords is shown on anenlarged scale, wherein 1 indicates the rubber strand which may beunderstood as naked rubber or as rubber having a winding of cotton. Sucha Winding, however, if provided is not to be confounded with thecoveringof the strand with which my invention deals. The latter coveringis indicated by 2 and is preferably composed of a single thread wroughtinto a chain stitch as shown, the loops of which embrace or surround therubber strand 1, the dotted lines indicating that part of the threadwhich passesaround the hack of the strand 1. One of the, threads 2 isapplied individually to each of the rubber strands and simultaneouslywithflihe formation of the loops they are interlocked withcross-tl'u'cads 3 which extend back and forth between the coverings 2 ofadjacent strand.- 1 interlocking: with each. The rross-thrcsuls 3 whichmay be double, although shown single, are thus arranged in successiveloops between the adjacent rubber strands. These loops are laid ingroups with intervening spaces 4 and are staggered upon opposite sidesof each cord producing a checker board open effect in the fabric. Theloops in the threads 3 being arranged at right angles to the directionof the extension and contraction of the rubber strands, will readilyopen and close with movements of the rubber and will not oppose thestretching and contracting of the fabric. The spaces 4 between thegroups of cross threads are formed by carrying the last run of thread ina group across the rubber cord to the opposite side thereof toform agroup on that side and again across the seine cord to the first sideWhere another group is formed and so on throughout the fabric, thusforming spaces alternating with. the groups of loops and of the samesize and shape. Eveother cord as a, a, a, etc., is thus crossed gy theloop threads 3 while the alternate cords b; b, b, etc, are merelyinterlocked with the tips of the loops carried by the cords w.

This fabric canbe out at any point and in any direction as may berequired iii-the making of articles or wear, without retraction orslipping of the rubber; it may be made of any weight desired. and may begiven any degree of porosity to suit requirements; it can be made on a,machin it conse uent low cost and the peculiar stitch afl'or s a way ofincolgmrating rubber in what is the equivalent 0 a knit fabric with outliability of displacement of the rubber.

I claim:

I. An elastic textile open'work fabric comprising a series of parallelelastic cords spaced apart, an indiv dual textile covering for eachcordand cross threads connecting open spaces.

2. An elastic textile open-work fabric comprising a series of parallelelastic cords spaced apart, on individual textile covering for each cordan-:l.cross threads connecting the coverings of adjoining cords, saidcros threads being run back and forth. in close relation forming groups.with intervening open spaces, the groups on one side of a cord being oposite an open space on the opposite side t ereof.

3. An elastic textile open-work fabric comprising a series of parallelelastic cords spaced apart, an individual textile covering for each cordand cross threads connecting the coverings of adjoining cords, saidcross threads being run back and forth in close relation forming groupswith intervening open spaces, the threads composing the groups on theopposite sides of alernate cords being utinuous.

In witness whereof I subscribe my signature.
